+# WORKED-OUT EXAMPLE FOR RSASSA-PSS
+# =================================
+#
+# This file gives an example of the process of
+# signing a message with RSASSA-PSS as
+# specified in PKCS #1 v2.1.
+#
+# The message is an octet string of length 114,
+# while the size of the modulus in the public
+# key is 1024 bits. The message is signed via a
+# random salt of length 20 octets 
+# 
+# The underlying hash function in the EMSA-PSS
+# encoding method is SHA-1; the mask generation
+# function is MGF1 with SHA-1 as specified in 
+# PKCS #1 v2.1.
+# 
+# Integers are represented by strings of octets
+# with the leftmost octet being the most
+# significant octet. For example, 
+#
+#           9,202,000 = (0x)8c 69 50.
